Listening to the Nanopores : Smart Nanomaterials Use Humidity to "Tune" Hypersound Like a Guitar String

What if humidity could act as a control knob for hypersound ? Researchers have shown that nanometer-scale pores in thin films can “sense” moisture in the air and dynamically change how they trap sound, turning ordinary water vapor into a tool for controlling vibrations at the nanoscale. Nanophononic devices — structures that control sound at the nanoscale — are emerging as key components for ultrafast signal processing, telecommunications, …

C2N organizes its first Rendez-vous Techno

C2N hosts one of the largest academic nanotechnology facilities in Europe. Technology and nanofabrication are therefore at the core of its activities, along with the skills and expertise of those who develop them. This first Tech Meeting, held on Thursday, April 9, was designed as a key moment to highlight these activities and the work carried out within the facility. The event was structured around oral presentations and a poster …
